Question

test rievew(help )1)Suppose div(F⃗ (−3,−2,4))=−120. Estimate the flux of F⃗ out of a small, outward-oriented box of side length 0.2 centered at the point (−3,−2,4) with edges parallel to the coordinate axes.

Flux ≈

Answer 1

It's a closed box? \[
\iint_S \mathbf F\cdot d\mathbf S = \iiint_V \nabla \cdot \mathbf F\;dV
\]

Answer 2

iam not sure
